  • stop faces on both sides are dimensioned and aligned in such a way that the clamping bodies of each ring in their swivel end positions define with their tips a circular line whose diameter is less than or at most equal to the inner diameter of the winding core d w , while applies to an area defined by the center positions that are available in their clamping body tips circular line that the resulting diameter d t is greater than w, the winding core inner diameter d.
  • each clamp body is not supported on a lateral contact surface of a ring recess, but with its cylindrical base body on the base of the recess, it is advantageous according to a development of the invention according to claim 2 if the clamp body tip has a the winding direction circumferential force F u1 or F u2, which is opposite to the direction of rotation D 1 or D 2 of the drive shaft, encloses an acute angle ⁇ , so that the clamping body is close to its swiveling end position and its tip can get caught on the inside surface of the winding core accordingly.
  • each recess in a ring for receiving a sprag axially symmetrical to an axis of symmetry formed by a radial beam the dead center position of each sprag is aligned with the radial beam.
  • a roll cutting and winding machine 1 in which a supply roll 2 a material web 3 drawn off and by side by side Cutting knife 4 divided into a number of strip-shaped bands 5 becomes. These are wound on friction winding shafts 6, 7, respectively a band on the one friction winding shaft 6 and the adjacent band the other friction winding shaft 7 is wound up.
  • Friction winding shafts 6, 7 From a side view one of the identical in construction Friction winding shafts 6, 7 according to FIG. 2 and additionally from FIG. 3 can be seen that they each consist of a central drive shaft 8 with three There are circumferentially offset longitudinal grooves 9, in each of which one pressure bar 10 pointing towards the outside and an inflation hose 11 are used are. Of course, alternatively more than three longitudinal grooves can be used each included pressure bar 10 and inflation hose 11 may be provided.
  • Rings 12 are attached to the drive shaft 8, their construction in detail 3 and 4 is shown in more detail. Between them are thin washers 13, preferably corresponding to the outer diameter of the rings 12, used. The rings 12 lie against one another via the washers 13 tight and rotatable and are laterally on threaded sections 15 screw-on clamping washers 14 held together in the axial direction.
  • Tubular winding cores 16 are attached to the rings 12, with the aid be resiliently biased core holders 17 held.
  • the rings 12 are so narrow that usually from a winding core 16 several of them are covered.
  • front-side pins 18 each is Friction winding shaft 6.7 in side cheeks 19 of the roll cutting and winding machine 1 added. This is also done via not shown Drive elements of the drive (arrow 20) of the friction winding shafts 6, 7.
  • each ring 12 is concentric in two mutually arranged ring elements, namely an inner friction ring 21, preferably made of metal, and an outer retaining ring 22, preferably made of a plastic material. There is no one between the two Relative movement possible. While on the inside of the friction ring the Apply pressure strips 10 takes the retaining ring 22 distributed over its circumference the core holders 17 on. In the exemplary embodiment there are five winding core holders 17 (distributed at a distance of 72 ° seen over the circumference) intended.
  • the sleeve-shaped winding core 16 which usually consists of paper (cardboard) or plastic and has an inner diameter d w slightly larger than the outer diameter d a of the holding ring 22, is attached to the holding ring 22. This results in between the outer ring surface 23 and the winding core Inner surface 24 a small distance.
  • Each winding core holder 17 consists of a spring-loaded rotating part in Shape of a clamping body 25, which in turn has a cylindrical shape Base body 26 and an adjoining clamp body tip 27 has.
  • the cylindrical one Base body 26 is supported on an equally cylindrical base 28 from a recess 29 machined into the outer surface 23 of the retaining ring, which opens in a funnel shape and thereby left and right stop surfaces 30, 31 has to which the edges of the clamping body tip 27 when pivoting (Swivel axis 32) to the system.
  • the tip angle ⁇ of 54 ° has been found to be particularly advantageous for the functioning of the invention proven if an opening angle ⁇ of the recess 29 of approximately 30 ° (cf. Fig. 3) is provided.
  • Each clamping body 25 is, and this is particularly apparent from Fig. 5, in Provide the area of the sprag tip 27 with bevels 33 on both sides, which preferably have an inclination (inclination angle ⁇ ) of 45 °.
  • the Clamping body 25 is also equipped with a notch 34 which the inclusion of a spring wire 35 is used to the clamping body 25 in a desired starting position, its dead center position.
  • the notch 34 is orthogonal to a radial beam 36 aligned from the friction winding shaft axis 37, axis of symmetry. This results in a radial beam symmetrical arrangement or dead center position of each clamp body 25.
  • the spring wire ensuring this 35 is on the one hand in the notch 34 and on the other hand in a recess 38 of the retaining ring 22 is inserted, where it is supported at each end can.
